- 1/2 teaspoon scraped Castile soap
- 1/2 – 1 teaspoon boiling water
- 1 beaten egg white
Pour boiling water over the scraped soap, and wait till the soap is dissolved. Then add the soap solution to the beaten egg white.
The original Edwardian shampoo recipe says to scrape a cake of Castile soap and mix it with a pint of boiling water. But as I didn’t know what weight their cake of Castile soap had, I’ve mixed about one part soap with one part water. Castile soap is either a liquid or hard soap made from olive oil. The Edwardian shampoo seems to use hard Castile soap. In my country, there’s no Castile soap to buy, so I’ve used Aleppo soap which seems to be about the same. The Aleppo soap I’ve used is also made from 100% olive oil and without laurel oil.
The shampoo has about the same cleaning power as the egg yolk shampoo. I’d double the amount of shampoo the next time. The shampoo and washed hair has hardly any smell, neither good nor bad. The shampoo is easy to distribute – just like ordinary shampoo – because of the beaten egg white. The shampoo gives volume to the hair, but the hair isn’t as is easy to detangle as after using the egg yolk shampoo, probably because of the soap content.
